LEDGER-INDEX.

SPECIFICATION forming part of Letters Patent No. 603,944, dated May 10, 1898.

Application filed September 30, 1897. Serial No. 653 ,641. (N0 model.)

T0 at whom it may concern:

Beit known that I,WILLIAMM.DALY, a citizen of the United States, residing at Philadelphia, in the countyof Philadelphia and State.

.tion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to index attachments for account-books, such as bankledgers, whereby the state of the account or balance remaining or due can be ascertained at a glance; and it consists in the combination, with an account-book, of one or more readily-detachable slates or sheets of pasteboard covered with a silicious coating.

My invention further consists in the construction, combination, and arrangement of parts more fully described hereinafter and specifically pointed out in the claim.

In the accompanying drawings,forming part of this specification, Figure 1 shows an opened ledger having my improved index in position thereon; and Fig. 2, an end view of a closed book, while Fig. 3 shows the index and its frame detached from the book.

In the drawings, A represents the ledger, the covers B and G of which project beyond the leaves D of the ledger. Interleaved with these are stiff sheets E, which project beyond the edge of the ledger-leaves nearly or quite to the edges of the covers. Attached to each of these sheets E is a light metallic or sheetmetal casing F, having its two side edges f f and its upper edge 9 upset, so as to form a receptacle,in which the slate H may be readily inserted. This metallic frame F may be attached either by cementing it to the sheet or it may be attached with light rivets, so as to become a permanent fixture not readily detached or displaced.

It will be seen that the slate H maybe used to carry the balances of several accounts and that when it is desirable or necessary to make an erasure or any other change on the slate it is readily slipped from its position in the holder, and after the correction is made it is replaced in its original position,and if through use or accident the slate becomes worn or injured a new one can be utilized without in any way injuring the book. It is evident that the slate can be used on either side by simply withdrawing it and inserting with the reverse side up.

Having described my invention, I claim The combination with an account-bookhaving sheets projecting beyond the edges of the leaves of the book, of the retaining-frames secured to said extended sheets, and the slates adapted to slide within and be retained in position by said frames, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM M. DALY.
